SPECIFICATION forming part of Letters Patent No. 480,499, dated August9, 1892.

T0 on whom it may concern.-

Be it known that I, ALFRED A. HOUGHTLIN, a citizen of the United States,and a resident of the city of Brooklyn, in the county of Kings and Stateof New York, have invented certain new and useful Improvements inAttachments to Roll-Carrying Spindlesfor Web-Printing Presses, of whichthe following is a specification.

The usual method of printing newspapers upon the rapid web-presses wasto dampen the paper before running it through the press. This was doneby running the paper ofi from the shell or core upon which it was woundat the paper-mill and winding it upon a shell or core which was fittedperfectly to the spindle of thepress on which the paper was to be used.This rewinding of the paper was very expensive and troublesome and ledto the adoption of the present method by which the paper is printed fromthe roll just as it comes from the paper-mill without moistening orrewinding it. To do this requires that the roll of paper shall becentered perfectly, so that the paper shall run off evenly and true andunder a proper tension. If the roll be not centered exactly, the paperis run off in a jerky manner and the proper feeding of the press isimpossible. Besides the paper often breaks by reason of the jerky unevenstrain on the same, so that much time is lost and paper wasted, as thepress has to be threaded again before starting. The immense editions ofthe morning papers require that all operations be accomplished quickly,and that a new roll of paper he put in place and adjusted within aminute or two at most, so as to be held firmly and run off true, and, asis often the case,-

changed on its spindle for the margin once or twice for each roll. Asthe rolls with their cores or shells are supplied from differentpaper-mills, and as the cores are of different sizes and lengths andonly alike in having a recess in each end, the spindle that carries themin the press must be so made that the centering and adjusting of theroll canbe quickly and perfectly done with any core or shell.

This invention is therefore designed for the purpose of providing theroll-carrying spindles of newspaper printing-presses with an adjustableattachment by which any size of core or shell can be quickly attached toits supporting-spindle, and by which the roll can -also be readilyadjusted and centered to the required position on the spindle with greatfacility.

The invention consists of the combination, with the roll-carryingspindle, of acollar having a tapering inner portion attached near oneend of the spindle, said collar being provided with a sliding oradjustable key that is guided in a longitudinal recess of the collar andadapted to engage the ordinary recess in the end of the core or shelland a second tapering collar which is arranged near the other end of thespindle and clamped firmly to the opposite end of the core or shell by ascrewnut that turns on a threaded sleeve which is attached by aset-screw to the spindle, so that the collar clamps the core rigidly inconnection with the tapering collar at the opposite end, as will befully described hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation ofthe roll of paper as applied to the spindle of a printingpress. Fig. 2is a side elevation of Fig. 1. Fig. 3 is a side elevation of theroll-carrying spindle and its connection with the core or shell of theroll, this figure being drawn on a larger scale. Fig. 4 is a verticallongitudinal section of Fig. 3; and Figs. 5 and 6 are verticaltransverse sections, respectively, on lines 5 5 and 6 6 of Figs. 3 and4.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the roll-carrying spindle of aweb-printing press such as are used in large newspaper printingoffices.The spindle A is provided at one end with a collar B, that is attachedthereto by a suitable set-screw b, said collar being made ofconically-tapering shape and provided with a longitudinal recess b, inwhich an adjustable key 0 is arranged which is provided with a set-screwd and with a second screw or nin d, the head of which engages a recess din the end of the core or shell D of the roll of paper, as shown clearlyin Figs. 3 and 4. The opposite end of the core or shell D is supportedon a conical collar D, that is loosely applied to the spindle A andclamped firmly to the opposite end of the core or shell D by anadjustable screw-nut D that may be readily adjusted on the threadedsleeve D of an enlarged collar D which is attached by a set screw 6 tothe spindle A", as shown in Fig. 4. When a new roll of paper has to beplaced on the spindle, the collar D' and the collar D with the screw-nutD are removed and this end of the spindle passed through the core orshell of the roll until the collar B abuts against the opposite end ofthe core or shell. The key 0 is then adjusted so as to engage the recessin the core or shell D. The core is then firmly secured in position byslipping the loose collar D over the opposite end of the spindle, alsothe collar D, with its screw-nut D and attaching the collar D by itsset-screw e to the spindle. The screw-nut D is next moved forward on thethreaded sleeve D and the conical collar D tightly movedup against theend of the core, so that the roll is thereby centered and firmly securedin position on the spindle. In case the roll should not be in properposition to give the proper margin on each side of the printed sheet, itcan be readily shifted on the spindle by loosening the setscrews of thecollar B and D so that the entire roll with its core and the attachingdevices of the latter can be readily shifted on the spindle until theroll is in the position required for use, when the collar B as well asthe collar D are clamped again to the spindle and the screw-nut movedup, so as to tighten the collar D' to the core. The collar B- isconnected with the spindle A by a groove f in the collar, which movesalong a spline f on the spindle, as shown in Figs. 3 and 5, so that thecollar B can be adjusted longitudinally on the spindle but not shiftedaxially thereon.

The advantages of my fastening device for the cores or shells of paperrolls are that cores of different sizes can be quickly and convenientlysecured to the spindle of the printingpress; secondly, that they can bereadily adjusted on the spindle for the proper margin afterbein g placedin position thereon; thirdly, that the core with the roll is reliablycentered, so that the paper is delivered evenly and without jerks, and,lastly, that the core or shell can be removed with great facility afterthe paper is unwound from the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. The combination, with theroll-carrying spindle of a web-printing press, of a tapering collarsecured to one end of the spindle, a locking-key guided in alongitudinal recess of said collar and adapted to engage a recess atthe'end of the core or shell of the roll of paper, a loose conicalcollar adapted to engage the opposite end of the core or shell, and

, means for clamping said collar to the end of the core or shell,substantially as set forth.

2. The combination, with a roll-carrying spindle of a web-printingpress, of a tapering collar secured to one end of the spindle, said Icollar being provided with a longitudinal recess, an adjustable keycarrying a projecting pin or screw guided in said recess and adapted toengage a recess in the end of the core or shell, a tapering collarplaced loosely on the other end of the spindle, a threaded sleeveattached to the shaft near said collar, and a screw-nut applied to thethreaded sleeve, so as to clamp the tapering collar to the other end ofthe core or shell, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
